Cashew Plant Indoors: Nearly Impossible in Nebraska

Bobbi's cashew seedling (1 month) shows brown leaf curl and trunk spots. Pot by drafty sliding door under heat vent in Nebraska winter.

Fundamental Mismatch

Cashews (Anacardium occidentale) are tropical, needing:

• No cold tolerance
• Intense direct outdoor sun (indoor light far weaker)
• High humidity

Success indoors outside greenhouse is near-impossible. Symptoms (brown spots, curl) = generic stress from light/draft/humidity/water issues.

Why Cashews Aren't Houseplants

No margin for error. Small pot, sunniest window, precise watering—and still minimal success chance. This explains why they're not sold as indoor plants.
